2 Claims. 1

This invention relates to gas heaters.

The invention is more particularly concerned with an improved radiantconstruction for removable disposition over a gas burner in a suitablestove construction.

A primary object of the invention is the provision of a sheet metalradiant of cylindrical form for vertical disposition over a gas burnersuitably arranged in a stove body.

A further object of the invention is to provide an elongated sheet metalcylindrical radiant having a multiplicity of relatively small aperturesin the wall thereof, and the radiant having supporting means forremovable disposition over a gas burner with its lower end in verticalspaced relation thereto.

A still further object of the invention is to provide a radiant in theform of a cylindrical shell constructed of stainless steel and which iscapable of expeditious manufacture and is capable of long use while atthe same time being capable v of radiating a maximum of heat.

Other objects and advantages of the invention will become apparent inthe course of the following detailed description taken in connectionwith the accompanying drawing, wherein- Fig. 1 is a substantiallyvertical axial section through the improved stove with one of the frontsliding doors being partially shown in front elevation.

Fig. 2 is a horizontal sectional view in the plane of line 22 on Fig. 1and on a reduced scale.

Fig. 3 is a horizontal sectional view in the plane of line 33 on Fig. 1and on a reduced scale.

Fig. 4 is an axial vertical section of the upper portion of theincandescent member or radiant.

While the body of the stove including the outer shell may be of variousforms, a desired construction for use of the improved radiant orincandescent member comprises a suitable circular base l provided withsupporting legs I l.

The upper end of the base is suitably rolled or otherwise formed toprovide an inner vertical flange l2 and a curved portion providing incombination with flange I2 a circular track l3.

The outer shell may desirably comprise a rear semi-cylindrical portion[4 and a pair of foraminous sliding front doors l5, both of which areshown closed in Fig. 3 and only one of which is shown partially closedin Fig. 1.

The outer shell further comprises a circular upper portion I6 having avertical flange I1 and a circular track l8.

The rear portion is suitably secured to flanges l2 and I1 and the doorsare slidably supported 2 at their lower and upper edges in the tracks l3and I8.

The upper portion l6 includes an inwardly directed horizontal flange l9to which is secured the horizontal flange 20 of a drum member 2| whichis provided with suitable openings 22 throughout its circumference.

A cover member 23 is removably supported on drum member 2| and isprovided with a circumferential series of openings 24 in its otherwiseclosed top Wall 25.

A burner 26 is disposed in an aperture 21 in a plate 28 suitably securedto flange l2. The burner may be supported in position by a bracket 29suitably secured to the bottom of plate 28.

A circular baflle plate 30 is supported within drum member 2! adjacentthe top thereof as by means of legs 3| whose lower ends rest upon andare suitably secured to flange I9.

An important feature of the present invention resides in the improvedmetal radiant or incandescent member 32. It is preferably formed ofstainless steel and is stamped out, perforated, and bent to proper form.This member is disposed axially of the outer shell including portions l4and I5, and it is disposed vertically as indicated in Fig. 1.

The member 32 is in the form of a cylindrical shell which is open at itslower end and closed by a flanged disk 33 at its upper end and thecylindrical wall of the shell is provided with a multiplicity of smallapertures 34.

The shell 32 is provided with a tongue 35 at its upper end and which isrigidly supported on the cylindrical wall thereof.

The tongue 35 is provided with an aperture 36 for removably receiving ahook 31 depending from and suitably secured to the bafile plate 30.

The tongue and hook provide a suspension for the shell 32 with its openlower end disposed a relatively short distance above the burner 26 as isindicated in Fig. l.

The lower end of the shell is provided with a pair of diametricallydisposed legs 38 insertable in openings 39 in the plate 28 formaintaining the shell in proper vertical position above the burner 26.

It is to be particularly noted that the member 32 has its lower end insubstantial spaced relation to the burner 26 whereby providing foradmission of air to the inside of the radiant which is necessary forcomplete combustion of the gases.

While I have disclosed my invention in accordance with a single specificembodiment thereof,

such is to be considered as illustrative only and not restrictive, thescope of the invention being defined in the sub-joined claims.

What I claim and desire to secure by U. S. Letters Patent is:

1. In a gas heating stove including a generally cylindrical verticalwall and a top cover, a horizontally disposed burner supportedsubstantially axially of said wall and adjacent the bottom theijeof; asheet metal cylindrical radiant disposed over said burner insubstantially coaxial relation to said wall, and means for removablysecuring the radiant within the stove, said stove including ahorizontally disposed baflle adjacent said top cover and a horizontallydisposed plate adjacent the bottom of the wall, said means comprising acooperating hook and tongue on the baflle and radiant for suspending thelatter from the baiile, and said means further comprising a pairof legsdepending from the lower end of the radiant and removably received inapertures in said plate.

2. A radiant for use in gas heating stoves comprising a sheet steelcylinder provided with apertures in the wall thereof, one end of saidcylinder being open for disposition over a gas burner and a flanged diskclosing the other end of the cylinder, together with Supporting means onthe radiant comprising an apertured tongue adjacent said disk and a pairof legs adjacent the open end of the cylinder.
